Cleaned Solar Arrays Gleam in Mars Rover's New Selfie

A self-portrait of NASA's Mars Exploration Rover Opportunity taken in late March 2014 (right) shows that much of the dust on the rover's solar arrays has been removed since a similar portrait from January 2014 (left). Both were taken by Opportunity's panoramic camera (Pancam).
